The lifting components include a permanent magnet lifter 7 and a connecting belt 8. The lower end of one connecting belt 8 is connected to one permanent magnet lifter 7. The upper end of the connecting bracket is connected to the lifting ring 1, and the lower end of the connecting bracket is connected to the horizontal suspension rod 2;

[0018] The upper end of one connecting belt 8 is connected to one movable sliding sleeve 3. One movable sliding sleeve 3 is sleeved on one horizontal suspension rod 2. The movable sliding sleeve 3 can move back and forth along the corresponding horizontal suspension rod 2, and the fastener 4 can fix the movable sliding sleeve 3 at any position on the horizontal suspension rod 2.

[0019] The permanent magnet lifter 7 is also known as a permanent magnet lifting device or a permanent magnet chuck. The permanent magnet lifter 7 consists of a strong magnetic system made of high-performance neodymium iron boron permanent magnetic materials. Its working principle is based on Faraday's electromagnetic induction principle. It uses high-performance permanent magnetic material neodymium borate inside, which can generate a very strong suction force in the magnetic circuit. By flipping the handle, the magnetic force lines are changed to make the lifter in the working or closed state; it does not require external power supply and is a new type of lifting tool that is both safe, energy-saving, and highly efficient.

[0020] When using the balanced lifting device of the present utility model to lift a cylindrical workpiece 9 made of non-stainless steel material, first, hook the overhead crane hook into the lifting ring 1; then lift the entire lifting device as a whole so that the position of the permanent magnet lifter 7 is slightly higher than the top of the cylindrical workpiece 9 to be lifted; then, according to the diameter of the cylindrical workpiece 9, adjust the position of the movable sliding sleeve 3 on the horizontal boom 2 so that the permanent magnet lifter 7 is directly above the side wall of the cylindrical workpiece 9, and place the permanent magnet lifter 7 on the side wall end face of the cylindrical workpiece 9 through the overhead crane hook; finally, rotate the handle of the permanent magnet lifter 7 to make it in the working state, fix the cylindrical workpiece 9 and the permanent magnet lifter 7 together, and the overhead crane conducts the lifting work on the cylindrical workpiece 9.

[0021] Specifically, the horizontal boom 2 mainly plays a balancing and connecting role. In order to improve the balance of the entire lifting device, as shown in Figure 1 , the number of the horizontal booms 2 is three. One ends of the three horizontal booms 2 are connected together, and the included angle between any two horizontal booms 2 is 120°.
